Answer:
If the Franks had lost, Europe might have been Muslim instead of Christian.
Explanation:
The Battle of Tours in 732 is one of history's most significant battles because "If the Franks had lost, Europe might have been Muslim instead of Christian."
This is based on the fact that at the Battle of Tours near Poitiers, France, the then Frankish leader Charles Martel, a Christian, won the war against the large army of Spanish Moors, who are majorly Muslims, thereby stopping the Muslim invasion into Western Europe after conquering Spain at the time.
